Today on Ecléctico you're listening to Ibeyi, a French Afro-Cuban duo featuring twin sisters Lisa-Kaindé and Naomi Diaz. Their music is Caribbean gospel. The scraping rhythm of the percussion is a mesmerizing chant, calling voices from deep in the ground up into the humid air. Gambian-British rapper Pa Salieu adds verses you'll understand and some you won't. It will all make sense. There is shared cultural history here.
